Advances in cardiopulmonary bypass and euthyroid sick syndrome in children with congenital heart disease / 国际儿科学杂志

Thyroid hormones(TH), one of the human′s essential hormones, play a crucial role in the cardiovascular system.Studies have shown that hypothermia, blood dilution, vascular endothelial injury, ischemia-reperfusion, and inflammatory factor release during cardiopulmonary bypass may cause thyroid dysfunction, leading to the euthyroid sick syndrome(ESS). There is a close correlation between ESS and postoperative low cardiac output and elevated systemic vascular resistance, which seriously affects the prognosis of pediatric patients.Studies have shown that perioperative supplementation of thyroid hormones can reduce ESS levels, especially among pediatric patients and those children with complex congenital heart disease have apparent clinical advantages.However, the results from different clinical studies varied, and currently, thyroid hormone replacement therapy is under debate.This review examines the available literature on the clinical effects of thyroid hormone on the cardiovascular system and the relationship between ESS and cardiopulmonary bypass.The clinical evidence of the treatment of ESS is gathered and discussed with an intent to find a gap for further research.

Vaginal paravaginal repair plus vaginal bridge repair in treatment of female pelvic organ prolapse / 中国医师进修杂志

Objective To explore the effectiveness and safety of vaginal paravaginal repair(VPVR) plus vaginal bridge repair in the treatment of female pelvic organ prolapse (POP). Methods Sixty-five patients with different defects of pelvic floor underwent VPVR or plus vaginal bridge repair for posterior vaginal wall. Patients were followed up after operation. The cure rate was estimated subjectively and objectively. The patients' quality of life was evaluated by the pelvic floor distress inventory short form 20 (PFDI-20). Results All 65 cases were treated by vaginal hysterectomy and anterior vaginal repair, in which there were 33 cases underwent VPVR while 32 cases underwent VPVR plus middle area repair. Forty concomitant procedures for vaginal bridge repair were also performed. The average operative time was (110.00±20.12) min and blood loss was (119.52±45.33) ml. The symptom of stress urinary incontinence of 25 cases significantly released after operation. Four incision recovery delayed and there were no other complicatious occurred. Patients were followed up for 6-29 months,the objective cure rate was 100.00% (65/65) and subjective cure rate was 92.31%(60/65), and 58 cases (89.23%)improved significantly with the quality of life comparing with that of pre-operation by completing PFDI-20 (P<0.01). Conclusions It is an effective and safe procedure for VPVR plus vaginal bridge repair to correct median to severe anterior vaginal prolapse and posterior vaginal wall prolapse. More clinical trials are needed to evaluate their long-term outcome.
